Giving Waste New Meaning
Managing our solid waste and finding ways to minimize it remains a focus at all of Sappi North America’s mills.
The conversion of the Cloquet pulp mill to manufacture dissolving pulp resulted in increased quantities of lime mud due to the cooking requirements of this higher-purity pulp. The impact of this change can be seen in both the total solid waste to landfill and the tonnes of solid waste processed through the Cloquet Mill’s beneficial use program with local farmers. Lime mud and boiler ash are used as a soil amendment to help farmers raise the soil pH, improving growing conditions for certain crops. Looking forward, our engineers in Cloquet are analyzing ways to expand the capacity of the lime kiln, which will increase internal recycling of lime mud and decrease overall chemical consumption and waste to landfill.
